NONSLIP GUARD FOR AUTOMQBILE TIRES.

Application filed May 21,1920. Serial No." 383,065.

To all whom it may cmwem:

Be it known that I, GILES A. DO'I'Y, a

citizen of the United States, residing at Davenport, in the countyofScott and State of Iowa, have invented new and useful Improvements inNonslip Guards for Automoan exceedin ly, simple andefi'ective device ofthis description which maybe readily applied to an automobile wheel tireeither in sections or extended entirely around the tire.

A further object of my invention isto so construct the guard of platesand links, the

plates having their edges upturned certain of which acting as means forattaching the links all of saidupturned ends serving to take a hold uponthe road bed to prevent skidding; and

A further object of my invention is to provide simple and efiectivemeans for attaching the guard to the tire and securing it in position byembracing the felly and spokes of the wheel.

With these ends in view, this invention consists in the details ofconstruction and combination of elements hereinafter set forth and. thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains, may understand how to make and use the same, I will describeits construction in detail, referring by numerals to the accompanyingdrawings forming a part of this application, in which Fig. 1, is a sideview of a portion of an automobile wheel showing a section of myimproved guard applied thereto.

Fig. 2, is a plan view of Fig. 1.

Fig. 3, is an enlarged plan view of one of i the nonskid plates.

Fig. 4, is an edge'v ew of Fig. 3. Fig. 5, is an edge view of Fig. 3taken at right angles to Fig. I Fig. 6, is a plan view of one of thelink for coupling the plates together. 4 Fig. 7, is an edge view of Fig,6. i Fig. 8,.is a plan view of the side links. Fig. 9, is an edge viewof Fig. 8. Fig. 10, is a side view of the'attaching snap hook forsecuring the guard upon the wheel.

Fig. 11, is an edge view of Fig. 10.

In carrying out my inventionas here embodied, I provide a number ofplates 1 'in the general form of a cross having the edges 2 and 3thereof upturned for contact with the road bed, and these upturned edgesare undercut as indicated at 4 so as to provide for the attachment oflinks thereto, the edges 2 receiving the links 5 by which the plates areattached together making a chain, while the.

edges 3 receive the links 6 which lie crosswise of the tire 7 to whichthe short chains i 8 are secured for connecting these links- 6 togethercertain of the latter are also utilized for the securement of theattaching chains 9 which are intended "to pass around the folly of thewheel, their'ends being detachably secured together by the snap hooks10.

The snap hooks 1O consist of a body having a central groove 11 therein,here shown as being produced by forming the body of sheet metal and ahook 12 is pivoted at 13 I between the ears 14 formed on the body sothat the upper end thereof may swing into the groove.

15 represents a latch which 16 tothe body so that when the hook is swunginto closed position this latch may be turned down over the upper end ofthe book which is curved as indicated at 17 for that purpose therebysecurely holding the hook against accidental displacement, the upper endof the body also has pivoted therein the attaching eye 18 to which oneend of the short chain is secured. By this arrangement the short chains9 may be passed around the folly of the wheel their ends beingsecuredtogether by the snap hooks thus securely.

holding the guard upon the tire. When it is intended to use the guard insections as shown in Fig. 1, each of these'sections is secured to thewheel in such manner thatthe short chains 9 will stand at angles to eachother and bear against the spokes 19 of the wheel thus holding the guardagainst slipping in either direction thereby enabling it to act. as agrip upon the road bed when the wheel is being turned either forward orbackward; but when it is desirable to extend the guard around the entiretire the short chains may be set at any desired an is since a slighttravel of the guard upon I: e tire will not be objectionable.

B'y the use of my improvement should any section of the guard break orbecome unduly is pivoted at I tion, what worn it may be readily replacedby uncoupling the links, removing one or more of the plates andsubstituting new ones therefor, thereby lessening the cost ofmaintaining an efiective non skid device upon an automobile wheel.

Of course I do not wish to be limited to the exact detailsofconstruction as herein shown as these may be varied within the limits ofthe appended claims without departing from the spirit of my invention.

Having thus fully described my inven- I claim as new and useful is 1. Anon-slip guard including a series of plates, each plate having fourradiating arms, road engagmg elements formed intememos gral with saidarms and projecting from their outer ends at right angles thereto, allof said road engaging elements having oppositely disposed undercutrecesses in their side edges andlinks engaging elements and resting insaid recesses.

2. A nonskid' guard for automobile wheels including a plate in the she eof across, portions of the arms of said p ate being upturned to produceroad engaging projections andhaving the side edges thereof undercut forthe purpose stated.

In testimony whereof,- I have hereunto afixed in si ature.
